To a/Z whoml it may concern:

Be it known that I, Joiiiv `W.BOOTH, a citi'-N zen of ythe UnitedStates, residing at lVash4 ington, Franklin county, Missouri, have invented a certain new and usefullmprovement in Type-,Writing-Macbines, of'which thefollowing is a full, clear, and exactvdes miption, such aswill enable others skilled inthe art to which it appertains tomake anduse the same, i

reference being `had 'to' the vaccompanying drawings, forming part of,thisfspeciiication,

-in whichfigure l. is .atop plan view of. theI ribbon.

"Fig, 3 is a fragmentary detail looking from above, the`,rollers being shown in section, talren through the grooves thereof.-Fig d is afragmentary elevation, partly in section, of the inner end of.theribbonreceptorcle;` andllig. 5 is an endY elevation showing saidinner end of thefvribbon-receptacle. l d r u rlhis invention relates `totype-writing mau mechanism of such machines.,

fdp object is to provide a typewriting machines, and more particularlyto the ribbon i chine with. 'a ribbon mechanism fdr endless ribbons,ythe storagereceptacle being of simple and convenient construction andthe feeda rolls being so -locatedvvith respect to the re.- ceptacle thatthe incoming ribbon is engaged by first one roll and ,then the otherfora considerable time after the ribbon enters the receptacle, wherebythe ribbon -is evenly-laid in the receptacle in layers of substantiallyuniform length, thus storing the ribbon in the receptacle in such mannerthat it can be uniformly withdrawn from the receptaclea vlo these endsand also to improve generally upon devices of the character indicatedthe invention consists in the various matters hereinafter described andclaimed' in the embodiment of the invention illustrated in theaccompanying drawings the mechanism is shown as applied to an Under- -isdriven in a given direction.

Asuch a' drivingshaftl being commonly applied to ribbon mechanisms andthis shaft v being usuallyfoperated by the type-bars., As

here shown, vthe driving-shaft i is provided with a gear 5,-which mesheswith a pinion 6 upon the shaft T, upon whichone of the driving-rolls ilis amounted, saidshaft being preferably iixedly located-41. e.,journaledin fired supports. A The sh ft 8, which carries the cooperatingdriving-roll., is provided with a pinion 9,'which meshes with acooperating pinion l0 upon the said Vshaft 7, whereby through theconnections indicated the gear 5 serves tofoppositely drive the saiddrivingn I, rolls, thus resulting in the desired feed of the ribbon.Preferably the shaft 8 is journaled `in the arms of a pivoted frame 1l,whereby v erabie pertion of its vribbonl to the other side of therecaptar/ie.v

The driving-rolls 3 project -for a considerable distance into theopen end of said receptacle, and aoonsiderable portion of theperipheryof each of said guide-rolls within the receptacle is exposed tothe incorning ribbon. Guide-arms le', projecting -inwardly from the sidevweils of the lreceptacie, are received in circumferential grooves l5 inthe drivingrroiis. ribbon having been initially laid in the receptaceacts somewhat as a` spring and tends to press against the arms le andinner portiens oi. the driving-mils 3.
